RAW-STOCK DYE VAT.

Application filed May 21,

To aZZ whom it may concern:

Be it known that I, FRANK M. MORTON, a citizen of the United States, residing at Phenix City, in the county of Lee and State of Alabama, have invented certain new and useful Improvements in Raw-Stock Dye Vats; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in raw stock dyeing apparatus and more particularly to those of the closed vat type in which the stock is supported in the vat on a perforated false bottom and is supplied with dye by means at the upper end of said vat.

One object of the invention is to provide a novel form of hollow head for closing the upper end of the vat, compressing the stock and distributing the dye liquor evenly, pre venting channeling thereof through the stock with resultant non-uniform dyeing.

Another object of the invention is to provide a novel association of parts whereby compressed air, or water or steam, may be admitted to the vat through a portion of the dye supply pipe, for the purpose of driving out surplus dye from the stock or washmg the latter preparatory to dyeing. A still further object is to provide effective means whereby the dyed stock may be quickly and easily ejected from the vat,

under the influence of fluid pressure.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure l is a perspective view of a dyeing apparatus constructed in accordance with my invention.

Figure 2 is a vertical sectional view taken substantially on line 22 of Fig. 1.

Figure 3 is a horizontal section as indicated by line 33 of Fig. 2.

In the drawings above briefly described, the numerals 1 designate a pair of duplicate dye vats operatively associated with a dye liquor tank 2 and a circulating pump 3. I preferably provide a single cover plate 4 for application to either of the vats 1 and when this plate is applied to one vat and the latter is operating, the other vat is open 1923. Serial No. 640,564.

foremptying and refilling, as will be clear by reference to Fig. 1.

Any suitable means may be employed for securing the cover plate 4 in place, but I prefer to provide a series of bolts 5 pivoted on each vat for this purpose, said bolts being receivable inperipheral notches 6 with which said cover plate is provided.

In the construction shown, each vat 1 is provided with a solid imperforate bottom 7 and with a perforated false bottom 8 which is adapted-to support the stock to be dyed, said vat being provided with dye outlet piping 9which may discharge either into the tank 2 or into some other outlet, according to the manner inwhich the valves 10 and 11 (Fig. 1) are set. The piping 9 is connected with the vat by a suitable coupling 12 having a comparatively small elbow 13 which leads from its exterior to its interior. A short pipe 14 is connected with the inner end of the elbow 13 and discharges into an appropriate coupling 15 positioned between the bottom 7 and the false bottom 8, and a discharge nozzle 16 rises from said cou plinq 15 through said false bottom. This nozzle, as will be hereinafter more apparent, is intended to supply compressed air to the vat l for the purpose of ejecting the dyed stock therefrom.

The side wall of the vat 1 is provided near its upper end with a dye liquor inlet passage 17 to which a supply pipe 18 leads from the pump 3, said pipe being provided with an appropriate cutoff valve 19 spaced a short distance from the vat. Suitable piping 20 having a cutoff valve 21, is provided for admitting water or steam into the pipe 18 between the valve 19 and the vat, when said valve 19 is closed and it will thus be seen that the stock within the vat may be effectively cleansed before the dyeing process. Additional piping 22 for supplying compressed air, discharges into the piping 18 between the vat 1 and the valve 19 and is provided with a cutoff valve 23 for each vat. Thus, by closing the valve 19 and opening the valve 23, compressed air may be admitted into the upper end of the tank to drive surplus dye liquor from the stock. A branch pipe 24 having a control valve 25, extends from the piping 22 and connects with the elbow, 13 for supplying the necessarv air pressure for ejecting the dyed stock.

A novel arrangement of parts is provide'd for evenly supplyingthe dye liquor to the stoclt, this construction being clearly illustrated in Figs. 2 and 8. The numeral 26 designates a horizontal plate below the cover plate 4', bothof these plates being declined from their peripheral portions to their centers. The space between the edgeseiithetwo plates is intended to communicate with the passage 17 to receive dye liquor from the latter and the lower plate 26 is provided with a multiplicity oflpei i orations 2? for evenly distributing this liquor to the stock. In the; preferred form ot-construction, the lower plate 26' is provided with a plurality. of upstanding fins 28 which contact with the coverplat'e 4 to space the two plates apart, said' plates being relatively secured by any'desired means, such as the central eye-bolt 29--passing through both of said plates. The eye of this bolt serves as means forconnecting a chain hoist or the like with the hollbW-head formed by the two plates, for the purpose of moving the latter from one of-the vats tothe other, a's occasion may demand,

'lShe construction of the hollow head formedby the. plates d and-26, is such that Wheirth-is'head' is" secured in place by the bolts tliestock is compressedin the vat to the proper extent to obtain the best dyeing results, This construction also "serves" to moreevenlydistribute the dyeliquor to the sto'ck, rhmr similar arrangements heretofore provided and it is thus insuredtl'iat the dye liquorshall not channel through certain restricted areas an'd'jproduce unevenf dyeing. Itlivillfbe seen that the liquor forced down+ wardly through the stock *will" discharge through the"p erforated falsebottoni 8 and the piping? and that circulation' may he carried onitor'any desiredl'ength Drums by properly (iQ lll' l'Qlllllg tlle several valves and the pump Thern to entirely drainthe vat, arrr, the period Of dye circulation, the valve sa ntl -be opened to admitcompressed 'air into, the upper end of'said vati 'llhus, all surplus,dye will be forced from, thefstock. lVhen now the \hollow head is detached from the: vat, the valve 25 an be opened and compressed air admitted: mder the dyed stock, whereupon the latter becomes iii effect, a pistonand isbodily inb ved upwardly and ejected from, the, vat. Thefvat' may "be washed after thedyeing operation by admitting water or steam from the piping 2Q and this wateror steam is also usable'forlclea irsing thest oclr before dyeing, ifdcsired,

From the foregoing, it will be seen that I have producednn exceptionally simple and compact apparatus forj'raw' stock dyeing, yet, regardless of this siinplicity,the apparatus has prove-n, to be exceptionally rapid and advantageous, Attention mayhere'be directed-to the fact thatby, having the plate 26 declined from its peripheral "edge to its center, insertion of this plate intethe vat 1, is greatly facilitated, as when any portion oi? said plate is engaged with the upper edge of the vat wall, the inclination ot the plate will assist materially in sliding the entire dye-supply head toward centered relation with! respect to the vat, permittin said plate to re'adily'enter the latter. Excellent results have been producednvhen using the construction herein disclosed and this construction may therefore be considered the preferred form of theinvention, but it isto be understood that withinthe scope oit'vthe appended; claims, numerous minor changes may be made. 7 v i I claim: a V
